T 'or/ZZ wir/0m `it concern:Y

Be it known thatwe, AUGUST SNYDnR and JOSEPH 1B. ConNoLLv, citizens of the United States, residing at Pittsburg, in the -county of AlleghenyandStateof Pennsylvania, have invented certain new and useful Improvements in Oondensers; and we do hereby deolare the following to be a full, clear, and exact description of the invention, such as Io will enable others skilled in the art to which itappert-ains to make and use the same. f Our invention has relation to, condensers of that lclass in which the exhaust from aI steam-engine is broughtV into contact with a x5 stream of water in a condensing-chamberat the upper' end of a stand-pipe, thecondensed steam and water falling down the stand-,pipe and tending to form a vacuum whereby the steam isl forcibly sucked from the exhaust` zo ports ofthe engine, thereby greatly increasing the ,efficiency of the engine. In apparatus ofthis class it has been found necessary to produce the best effect to draw off from thesteam `and Water any air which may z5 be carried thereby into the condensing apparatus; and ourinvention has for" its object the provision of novel means for condensing any steam or moisture which may be drawn off with the air, so as to prevent such steam 3o or moisture from entering the air-pump.

Our invention consists in the novel construction, combination, and arrangement of parts hereinafter described and claimed.

Referring to the accompanying drawing, which is a vertical sectional View of a condenser constructed according to our invention, A designates the exhaust-pipe by means `of which exhaust-steam is conveyed to the condenser from a steam-engine or other ap- 4o paratus. l

Oydesignates the condensing-chamber, to which thepipe is connected by an elbow B.

D designates the water-delivery pipe receiving a supply of water from a suitable water-elevating apparatus, such as a pump. The water-delivery pipe D is connected to an elbow J, that passes into the elbow B, the elbows J and B being preferably a single casting. 5o At the upper end of the water-delivery pipe D an air-chamber K is arranged, and above the chamberpK` isa small supplementary chamber 7c, fromwhich leadsla pipe 7o to the air-suction pipe M, the air passing on its way to said air-suction pipe through the upper end of a condensing-chamber L. A downwardly-opening valve W is arranged between the chambers Kand 7c, and the stem of the valve W has on its upper end a small upwardly-opening valve lw, that leads to the 6o open air, while the lowerend of the stem carries a float o. ,y

The elbow .l of the water-delivery pipe terminates within the condeusewchamber O in a funnel-shaped mouthtN, and. below the mouth N is a suspended` .bell O, having an upturned lip o, the bell being suspended on a rod P, that has a screw-thread upon its upper end that works through anut Q, beveled gears R S serving to turn the rod in the nut 7o and adjust the position of the bell. The bell O has a bushing T at its center through which passes the upturned end Uof an airpipe q, the purpose of pipe U being to draw olf the air which accumulates beneath the bell. i

The condensing-chamber L is composed of concentric cylindrical walls Z m, having between them aspiral passage L, through which the air passes on its way from the pipe U, 8o through which it is drawn from under the bell O. The exterior wall Zot the condensing-chamber L is formed with alarge number of radial fins or thin flanges Z tf, the purpose of which is to radiate and disburse as quickly as possible the heat which will be communicated to the wall Z by any steam that may be conveyed into the condensing chamber L with the air. The inner wall m of the chamber L is preferably made as thin 9o as possible and integral with the spiral o', Which forms the spiral passage for the air, and the interior wall m forms a straight passage fm, that extends entirely through the chamber L and permits of a free tlow of the outer air, by means of which the heat is rapidly conveyed away from said interior wall m and fromthe spiral o. A drain-pipe y leads from the bottom of the chamber L to the tail-pipe Y, and a trap W', that contains roo a shield W2, which is fixed over the exit of the trap, is connected to the drain-pipe y by a branch y.

Operation: The water from the Water-supply pipe issuing from the elbow J through the funnel-mouth N falls upon the bell() and striking the lip o is spread and falling over the lip and down through the condensingchamber C falls into the tail-pipe Y. The steam from the exhaust-pipe A, passing into the chamber C through elbow B, meets the water flowing from the funnel-mouth and which is spread out to the sides of the condenser-chamber() by the upturned lip of the bell O and is rapidly condensed, and the Water of condensation falls into the tail-pipe Y. The air is separated from the Water passing up the delivery-pipe D and passes into the air-chamber K, from which it is drawn off through valve W and thence to the top of the condensing-chamber L, through chamber k and pipe 7c', and thence to the air-suction pipe M. Any air that may be brought into the condenser-chamber C with the steam or water will accumulate under the bell O and will be drawn from under the bell by the pipe U and passing through pipe q to the spiral passage L and up through thelatter to its top and thence to the air-suction pipe M. Any vapor which may be drawn from the coudenser-chainber O into the supplementary air-cooled condensing-chamber L will be condensed in said chamber, and the resulting water of condensation will run down the spiral passage and be discharged into the tailpipe Y by the drain-pipe y. If under any circumstances vapor or steam should escape condensation in the supplementary condensing-cham ber L and pass over into the suctionpipe M, it will be condensed therein, and the resulting Water of condensation will be received in the trap W and drained off through branch y to the drain-pipe 'y and thence to the tail-pipe Y. If through an excessive supply the water should rise in the air-chamber K, the float 'u will rise with the Water and close valve W, thus preventing the water from passing into the air-suction pipe. When the valve W is closed, the valve w will be opened and air admitted from outside, which will break the vacuum and cause the valve W to open and the Water to sink in the supplypipe.

Having described our invention,we claiml. In a condensing system, the combination with a condensing-chamber, a water-pipe leading into said chamber, a tail-pipe and an air-exhaust pipe leading from said chamber, of an air-cooling chamber having entrance 6o and exit openings connected to said air-exhaust pipe and having its exterior surface exposed to and wholly cooledv by the outer air, substantially as described.

2. In a condensing system for condensing steam by direct contact with Water, the combination with acondensing-chamber, a steampipe and a water-pipe leading thereinto and a tail-pipe and an airexhaust pipe leading therefrom, of an air-cooling chamber connected to said air-exhaust pipe and formed with double walls and a central passage, the exterior surfaces of the outer wall and the central passage being exposed to the outer air so as to cool the air passing between the double Walls'wholly by radiation,substan tially as described.

3. In a condensing system for condensing steam by direct contact with water, the combination with a condensing-chamber, asteampipe and a water-pipe leading thereinto and a tail-pipe and air-exhaust pipe leading therefrom, of an air-cooling chamber connected to said air-exhaust pipe and formed with double walls and a central passage, the exterior surface of the outer wall and the interior surface of the central passage being exposed to and cooled wholly by the outer air and said aircooling chamber being provided with a pipe leading to the said tail-pipe substantially as described.

4. In a condensing system for condensing steam by direct contact with water, the combination with acondensing-chamber, asteampipe and a water-pipe leading thereinto and a tail-pipe and an air-exhaust pipe leading therefrom, of an air-cooling chamber located on a branch leading from said condensingchamber to said air-exhaust pipe said aircooling chamber being formed with double Walls havinga tort-nous passage between said Walls for the passage of the air to be cooled, a free central opening and radiating projections on the exterior of its outer wall, the said outer wall and the central passage being exposed to and cooled wholl)T by the outer air, substantially as described.

5. In a condensing system, the combination with a main condensing-chamber, a suctionpipe and pipe connections between said chamber and suction-pipe, of an air-cooler, on said connections a drain-pipe from said air-cooler, a trap on the connection between said cooler and the suction-pipe and a drain from said trap.

In testimony whereof we have affixed our signatures in presence of two witnesses.
